To what extent is the guys always have on the brain thing true?

To me, I only look at females my age or older. I'm 17 years old and if i notice a girl who I notice is clearly younger than me, I avoid any type of ual thoughts towards them as a reflex. Although i usually have on the brain nearly all day. I don't date people purely for and I think some people of the professions you mentioned above if they are truly respectful men of their practices, then they think the way I do towards their patients, friend's children etc.
